Is Hero The Palatial a solid investment for long-term ROI?

Builder track record is everything for investors, seriously. After years of paying rent, I'm finally looking to invest instead of just throwing money away. I'm checking out Hero The Palatial in Gurgaon, the price range is ₹4.55-5.44 Cr. My main concern is ROI. Has anyone tracked its capital appreciation since launch? Matlab, kitna upside dikhta hai long-term mein? Also, for a project in this segment, what's a realistic rental yield expectation? Not sure if 2-3% is even achievable here. And Hero ka residential delivery track record kaisa hai? On-time possession is crucial. Don't want my money stuck in an under-construction project forever. Any insights on their past projects' delivery timelines would be super helpful. Hoping this helps someone else too.
